Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164490, here are decompositions:

13 + 164477 = 164490
19 + 164471 = 164490
41 + 164449 = 164490
43 + 164447 = 164490
47 + 164443 = 164490
59 + 164431 = 164490
61 + 164429 = 164490
71 + 164419 = 164490

Showing the first eight; more decompositions exist.
